Open Coordinator has started to increase the number of coins being processed. Kruw coordinator seems to be receiving smaller amounts from the 1000+ it regularly used to process but nevertheless 300+ are still huge numbers.

Wasabi Wallet allows users to select a coordinator of their choice but Ginger Wallet forces users to use their coordinator therefore I am not surprised Ginger Wallet is on zero. Even if they are raising their free coinjoin threshold, the fact remains they will charge you 0.3% for using their service beyond the free limits.
